Projects per year
After obtaining a Geology BSc from Bristol University and a PhD in Sedimentology from Leeds University, Jan Alexander became a lecturer in the Geology Department of University College Cardiff (which became Cardiff University). In 1996, Jan was appointed Senior Lecturer in Sedimentology at UEA and promoted to Professor of Environmental Earth Science in 2009.
Jan's early research concentrated on tectonic controls on sedimentary processes (e.g. how rivers or ocean floor processes respond to tectonic activity), controls on sediments accumulation over long periods of time and the three-dimensional architecture of sedimentary rock types. Recently she has mostly concentrated on how sediment is eroded, transported and deposited in extreme events (floods and sub-aqueous gravity flows), and the diagnostic features in the deposits that might be used to recognise them in the rock record. Over the years, Jan has studied sedimentary processes and products in rivers, lakes, seas and oceans of North America, Australia and Europe, and also undertaken a wide range of laboratory experiments to understand aspects of the interactions between moving water and sediment.
Jan Alexander teaches at all levels within UEA including contributions to the undergraduate first year module "Understanding the Dynamic Planet", second year "Earth Science Skills" and "Sedimentology", third year "Fossil Fuels" and MSc "Research topics in Earth Sciences". She also supervises PhD students.

Key Research Interests
Sediment erosion, transport and deposition in extreme events (particularly high magnitude floods, submarine gravity currents); sedimentary bedforms and structures; tectonic and climatic controls on sediment distribution; geological record of environmental change.
The sedimentary processes and products of extreme events fascinate me. How is sediment eroded, transported and deposited in floods and sub-aqueous flows? What controls how sediments accumulate over long periods of time and how can studying modern events help the interpretation of the rock record? Over the years I have studied sedimentary processes and products in rivers, lakes and seas of North America, Australia and Europe, rocks ranging in age from Cambrian to Holocene, and also undertaken a wide range of laboratory experiments to understand fluid dynamical processes involved in sediment movement.
Current research projects include studies of; boulder movement in flash floods, sedimentary structure development in sand, Jurassic stratigraphy and palaeo-environment interpretation and sediment movement in tidal bores.
